Title: Improvements in or relating to the production of ª‰-methylmercaptopropionaldehyde
IPC: C07C325/00
Filed: 1946-09-26
Abstract: Beta-methylmercaptopropionaldehyde, which may be used for the synthesis of methionine, is obtained by reacting methyl mercaptan and acrolein at normal atmospheric pressure in the presence of a substance which functions as a catalytic agent and/or as a polymerization inhibitor, said substance comprising mercuric methyl mercaptide, copper acetate, benzoyl peroxide or hydroquinone.  It is stated that the reaction may be initiated at temperatures as low as 20 DEG  C. or as high as the reflux temperature of acrolein.  In examples: (1) acrolein is admitted into a mixture of methyl mercaptan and mercuric methyl mercaptide in a flask fitted with a brine-cooled reflux condenser.  An ice bath is applied when the temperature has risen to 75 DEG  C.  Distillation of the mixture yields b -methylmercaptopropionaldehyde; (2) as in (1) except that benzoyl peroxide is used and the temperature rises to 47 DEG  C. before applying the ice bath; (3) methyl mercaptan is passed into a mixture of acrolein and cupric acetate, the latter being transformed into a substance presumed to be cupric methyl mercaptide.  The mixture is finally distilled to obtain the product; (4) as in (3) except that hydroquinone is used in addition to the cupric acetate.  The Specification as open to inspection under Sect. 91 is not restricted to the use of a substance which functions as a catalyst and/or polymerization inhibitor and includes an additional example in which the product is obtained by passing gaseous methyl mercaptan into acrolein at 15-20 DEG  C. and at atmospheric pressure.  This subject-matter does not appear in the Specification as accepted.

Title: Electromagnetic device
IPC: H02K33/02
Filed: 1971-06-18
Abstract: 1348849 Plunger type reciprocating motors BENDIX CORP 18 June 1971 [18 June 1970] 28792/71 Heading H2A [Also in Divisions F1 and H3] An electromagnetic device such as an electromagnetic pump (see Division F1) includes a circuit arrangement in which energy released from the pump solenoid 23 during collapse of its magnetic field as a result of cut-off of a transistor 49 is dissipated at a controlled rate in a resistor 55 and a coil 25 arranged to allow current from the solenoid to flow through the coil and back to the solenoid. In the embodiment shown, initial current flow through solenoid 23 towards the emitter 49e of the transistor induces a voltage in coil 25 such that the transistor is driven toward saturation at which a plunger of the pump is driven to compress a spring. When the current in solenoid 23 reaches steady state, reduced conduction of the transistor results and the magnetic field of the solenoid begins to collapse. Instantaneous cut-off of the transistor is prevented by providing a discharge current path through the emitter to base junction, resistors 51, 53 and 55 and diode 57. A second current path through coil 25, resistor 55 and diode 57 ensures rapid, but controlled collapse of the magnetic field and quick release of the plunger. In another embodiment (Fig. 4, not shown), which enables the use of a higher voltage source, an additional path is provided for discharge of solenoid 23. A resistor (61) is provided in series with the diode 57 and a further diode (63) has its anode connected to emitter 49e and its cathode connected to the cathode of diode 57. In other embodiments (Figs. 5 and 6, not shown) the resistor and diode of the previous embodiment are interchanged (Fig. 5) thus permitting the use of a higher voltage transistor while reducing its operating temperature; and a diode (67) is connected to have its cathode connected to the emitter 49e and its anode connected to the base 49b. This diode acts to clamp the reverse emitter-to-base voltage at a safe level, and permits use of even higher voltages for short periods.

Abstract: 625,656. T r u e i n g grinding-wheels. NEWTON, E. P. (Gear Grinding Machine Co.). Oct. 31,1945, No. 28942. [Class 60] [Also in Group XXII] A mechanism for trimming cycloidal surfaces on grinding wheels by means of a trimmer point is provided with a pivot in its mounting member, permitting a limited rotation of said trimmer point when the mounting member is stationary to trace an arcuate curve, and an arcuate member fixed on a frame, the mounting member being constrained to roll about the periphery of the arcuate member so that the trimmer point moving therewith traces a cycloidal curve. The mechanism includes a frame C mounted between work centres D. D<SP>1</SP> and given the same rotation and axial movement as the work to be ground by the grinding wheel by means in which, Fig. 8, a rack bar P<SP>2</SP> engaging a stationary inclined bar Q at one end meshes with a gear train P<SP>1</SP> to rotate the frame C as it moves longitudinally. On a shaft E rigidly mounted in the frame C and concentric with the work centres is fixed a gear segment F on which rolls in mesh with it a gear segment F fixed on a shaft H journalled in a frame G pivotally mounted on the shaft E. Fixed to a head portion H<SP>3</SP> of the shaft H is a carrier J in which is rotatably mounted about a pivot J<SP>1</SP> in alignment with the pitch circle of the gear F' a support Ka, Kb for the trimmer K<SP>8</SP>. When the handle K<SP>5</SP>, attached to the trimmer support Ka is actuated it and the carrier J move about and with the shaft H which, owing to the meshing of the gear segments F, F<SP>1</SP>, also rolls about the gear F, and the tool K<SP>8</SP> thus traces out a cycloidal curve. Adjustable stops in the frame G limit the movement of the gear segment F<SP>1</SP> so that after part of a cycloid has been traced out the gear segments lock and the trimmer simply rotates about the pivot J<SP>1</SP> in the carrier J to trace out an arcuate path, an adjustable stop limiting this movement. The above described device traces out curves on a grinding wheel for grinding female work but a similar but slightly modified device will trace out curves on a wheel for grinding male work. Specifications 536,299 and 625,654 are referred to.

Title: Process for the production of electric resistance coatings
IPC: H01B1/24
Filed: 1935-10-23
Abstract: Electric resistances comprising a layer of carbon deposited on a suitable former from a gaseous carbon compound at high temperatures are obtained in a tubular furnace at atmospheric pressure in which air or other oxidizing gas is circulated about the former before carbon is deposited and the former is rapidly cooled after coating. The insulating formers are preferably fed into one end of the furnace in a series, so that the foremost former is preheated.  It is then pushed on to a device whereby it is turned about its longitudinal axis during the deposition of carbon, the carbon compound being fed from the opposite end of the furnace from the formers.  The treated former is then rapidly passed to the cold end of the furnace where it is cooled by the incoming gas stream, and during this period the next former moves on to the rotating device.  The cooled former is withdrawn through a suitable flap, and at the same time air is blown through the furnace to burn off all superfluous carbon and other impurities. When the flap closes, the carbon compound flows again and the cycle is repeated.
